A century-old mystery—and a desperate battle to survive—unfold in this standalone thriller from the New York Times bestselling author of Dark Matter and Recursion.   On Christmas Day in 1893, every man, woman, and child in a remote mining town disappeared, belongings forsaken, meals left to freeze in vacant cabins, and not a single bone found.   Now, journalist Abigail Foster and her historian father have set out to explore the long-abandoned town and learn what happened.
